Well.....now the review from the garden variety novice.... Got mine in Friday ..installed Saturday,,,, Great instructions ... Reading everything twice I still got it done with only one snaffu....I installed the MAF sensor in backwards (after the warning in the instructions) BTW if you do this it will start ok but not idle..just die..
my fit to the out side was good,, no leaks that I could detect...but I kept pressure
towards it while I tightened the well bolt...

I really was not preparred for the sound.... kinda like taking the air cleaner off dads old four barrrel ... but more air means more sound..

I can feel the diff when I get on it 3K and up but there seems to be slower throttle response below 3K ...maybe just me,,,

I believe that we need a good exhaust to maximize the effect...gotta get that air out !!
